Thank you everyone, undoubtedly the path has been less challenging than Tallfellas, allowing me to get to the end with a valuable extra enthusiasm that I believe has been crucial for the outcome, and that's sheer luck.
As Gully says, my first trophy ever, unfortunately it doesn't seem like it's possible to win unless you use 33+ players, which was the strategy I followed after the last "market exchange" of my team.
No idea how to build up from here, probably I'll go and change a couple of men.
